Workpiece bearer with own propulsive drive has only two wheels used to bear load with axles in plane transverse to transport direction and close to workpiece bearer center of gravity

摘要

The workpiece bearer (14) has an integral propulsive drive (18) consisting of a drive device (19) and wheels for a transport path system (12). The workpiece bearer has only two wheels (38a,38b) used to bear the load with axles in a plane (44) transverse to the transport direction (34) and essentially close to the center of gravity of the workpiece bearer.
